Abstract

The invention discloses a sound production device monomer, a sound production module and an electronic terminal. The sound production device monomer comprises a magnetic circuit system, a vibration assembly and a circuit board. The magnetic circuit system comprises a magnet yoke, a central magnetic part and a side magnetic part, the central magnetic part and the side magnetic part are arranged onthe magnet yoke, at least one of the central magnetic part and the side magnetic part comprises a permanent magnet, a magnetic gap is formed between the central magnetic part and the side magnetic part, and a containing groove is formed in the side, away from the magnetic gap, of the side magnetic part. The vibration assembly comprises a diaphragm and a voice coil, one end of the voice coil is connected to the diaphragm, and the other end of the voice coil extends into a magnetic gap of the magnetic circuit system; the circuit board is annular, and the circuit board is embedded in the accommodating groove of the magnetic circuit system. The sound production device monomer is more compact in structure, light, thin and miniaturized development is facilitated, and the accommodating grooves are designed in the peripheries of the side magnetic part, so that the effects of gathering magnetic induction lines and improving the magnetic field intensity in magnetic gaps can be achieved.

Description

technical field [0001] The present invention relates to the field of electroacoustic conversion, and more specifically, the present invention relates to a single sounding device; the present invention also relates to a sounding module and an electronic terminal using the single sounding device. Background technique [0002] The sound generating device is an important acoustic component in electronic equipment, which is a transducer device that converts electrical signals into acoustic signals.
